I have as a gag gift but I don't have a problem buying my friends toys, I'm just too broke to do it yet. My friend and I do plan on buying another friend of ours a good dildo and vibrator for Christmas.
I have shown my toys to friends, recommended things, and had a guy friend show me a toy I was looking into buying for my boyfriend. He even offered to share toys that have been sterilized, though I feel weird about asking! I would probably buy a toy for someone if I knew they would like it
